My area is American women's history.  Many Euro-minded types teach it starting with what my Native American colleagues call the Columbian Invasion.  But I love teaching it from the prehistoric period on our continent, i.e., I start with the First People.  My Native American students -- and I have many, in my area with the most rezzes east of the Mighty Muddy, and on one of the first campuses with NA studies -- rather like that start.  

Btw, on an urban commuter campus where students focus on college for jobs, I work a lot at tracking women's professions, employment, etc., too.  And as I have premed and nursing and health sciences students, I also have worked at learning about women in medicine.  You might enjoy that sort of course, Sam.  (You also might like a course taught by a colleague that is required for premeds on my campus: Race and Science in Medicine.)

Some events specific to women's history, though, include the first women's seminaries (soon colleges) in the 1820s; the rise of the first reform movements in the 1830s, as women led the way; the rise of the women's movement in the 1840s -- and especially the first women's rights convention in world history, in 1848 in upstate NY; the passage of the 14th and 15th Amendments in the 1860s that put the word "male" in our Constitution for the first time; thus, the rise of the women-only suffrage movement in 1869 -- when women first won the right to vote in one part of the country . . . and then the story for decades is "the struggle" to win the vote state by state by state until, finally, full federal suffrage with the 19th Amendment in 1920. . . .
